nVidia GeForce 7025: no screen resolutions higher than 800x600

[MichaelPeppers]

hrev38969 here, I'm using an nVidia GeForce 7025 nForce 630a with an old CRT screen. With the current nvidia driver I'm unable to set the screen to a resolution higher than 800x600.

In VESA mode I succeeded in setting the resolution to 1280x1024, also the official drivers in other operating systems have it working at 1152x864 with no problem at all.

Could be related to bug #2066 as far as I can tell.

Please attach a syslog.

Detection of GeForce 7025 was added in hrev38614.

Done, sir. =)

Syslog (a cleaner one)

Sh*t, I messed up the attachment system, sorry guys. The 3 syslogs are identical.

Extras cleaned up.

Great, thanks. If possible, please also create and attach an nvidia driver log file, there are instructions on how to create one in the readme file over here: ​http://dev.haiku-os.org/browser/haiku/trunk/src/add-ons/kernel/drivers/graphics/nvidia

Attached. Just took a look at it, the problem is signaled from line 698 onwards.

Hi,

The driver detects EDID/DDC successfully. It interprets the extra modelines reported only since on 99% (all but two I've seen sofar) screens here the max resolution it can display is reported. On this screen however this is not the case: it reports 800x600 here only.

This is the reason higher res modes are not offered in the screenprefs panel.

I don't think the nvidia.settings file supports a setting for disabling use of EDID yet.

There are three solutions to the problem:

• use another screen: your card is working properly :-)
• extend the driver to support to not use edid
• modify / extend the driver to also interpret the fixed modelines to find the highest possible mode. Probably Axel has something for that in his driver(s)?

Personally I currently don't have time to look further at this, sorry..

I would doubt that :-) But it would certainly be a good idea to have something like this. I would think the best way to implement this would be using the driver settings, as its a serious thing to override the monitor's reported capabilities, and will probably only be used rarely.

No worries, thanks for the explaination. I'll stick with VESA for now, since it works fairly good for my needs. (I'll have to buy another screen sooner or later, though ;) )

Hi there,

hrev49984 added a new nv.settings settings file setting called 'check_edid'. Set this setting to false to block the driver from preventing higher resolution modes from appearing in the ScreenPrefs app. This overcomes the problem of only being able to use low-res modes.

Be carefull not to use too high resolution modes though, as your monitor will not like that...

Closing ticket.

Bye!

Rudolf.
